ABS brakes have been a great safety feature of vehicle for many years now but when they are not working correctly they can make you wish we could go back to the days without them.



Daily Car Repair and Advice Tips Question 18 ABS Trouble

Dear Motor Medics,
 I have a 2001 Pontiac Grand Prix with the supercharged 3.8 engine. I had the car into the shop about six months ago and had the brakes repaired as they were grinding. They replaced pads and rotors on the front and rear and a passenger side axle shaft at the same time. Recently the abs and traction lights have started to come on then go off while I drive. They stay on for a few minutes to several days. Is there something related to the brake job or is this some new problem that needs to be addressed and what.

Dear Samantha,
 I don’t think that the brake work you had done six months ago is related to the problem you are having today. The brake pads and rotors are part of the mechanical brake system while the abs/trac light is part of the electronics of the antilock brake system. On many GM cars and trucks these lights will come on in this way and it is usually a sensor that has failed or more commonly a broken wire on one of the front speed sensors. If it is a broken wire some shops may choose to repair it instead of replacing the entire sensor which will save you money. The wires move a lot when driving so they are subject to break with age. Have your shop take a look and advise you of what is needed.

Take care, the Motor Medics
